Following recommendations from an IEA Greenhouse Gas R & D Programme (IEAGHG) workshop in September 2008: Defining R & D needs to assess environmental impacts of potential leaks from CO2 storage; hosted by the British Geological Survey in Keyworth, Nottingham; the IEAGHG Executive Committee approved the concept for a workshop in 2008 with an aim to focus on research on natural analogues for CO2 storage, using the IEAGHG Natural Releases of CO2 publication as a basis for the meeting.  Outcomes of the meeting are expected to be similar to that of standard IEAGHG Network meetings which provide gap analysis and R & D recommendations.  The workshop programme should therefore include international results from research projects representative of the current global knowledge base to enable effective discussion and research gap analysis.

Field Trip

The field trip day will begin at 8am with a walking trip around Maria Laach (approximately 6km) looking at the various sights and outcrops in the area, before heading to a few local springs.  Attendees will be provided with a packed lunch to eat in the field to add to the experience of being a field scientist for the day.  After lunch, participants will visit the Wallenborn geyser (in Eifel) – approximately a 135km round trip from Maria Laach. This geyser erupts regularly (around every 35 minutes) as the CO2-laden water forces its way to the surface. The water erupted here is cold at a mere 15°C.

On the return journey, attendees have the opportunity to have dinner at a local brewery, approximately 3km away from Maria Laach.

This will be an enjoyable and informative day, open to all attendees of the workshop.  To register for this field trip, we would kindly ask for a contribution of 55 Euros which cover your lunch and transportation throughout the day. For more details of the trip please click here
